The CS4341A is a complete stereo digital-to-analog system including digital interpolation, fourth-order deltasigma digital-to-analog conversion, digital de-emphasis, volume control, channel mixing and analog filtering. The advantages of this architecture include ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature and a high tolerance to clock jitter.

The CS4341A accepts data at all standard audio sample rates up to 192 kHz, consumes very little power, operates over a wide power supply range and is pin compatible with the CS4341, as described in section These features are ideal for DVD audio players.
